iOS中的Im元素谷歌驱动器显示错误
下的无法完成操作(com.google.GIDSignin错误 - 4。)
- (void)signIn:(GIDSignIn *)signIn
didSignInForUser:(GIDGoogleUser *)user
withError:(NSError *)error
我在下面的代码中添加了从textField
备份谷歌驱动器中的内容GIDSignIn* signIn = [GIDSignIn sharedInstance];
signIn.delegate = self;
signIn.uiDelegate = self;
signIn.scopes = [NSArray arrayWithObjects:kGTLRAuthScopeDriveReadonly, nil];
[signIn signInSilently];
// Add the sign-in button.
self.signInButton = [[GIDSignInButton alloc] init];
[self.view addSubview:self.signInButton];
// Create a UITextView to display output.
self.output = [[UITextView alloc] initWithFrame:self.view.bounds];
self.output.editable = false;
self.output.contentInset = UIEdgeInsetsMake(20.0, 0.0, 20.0, 0.0);
self.output.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
self.output.hidden = true;
[self.view addSubview:self.output];
// Initialize the service object.
self.service = [[GTLRDriveService alloc] init];
答案 0 :(得分:0)
错误表示钥匙串中没有身份验证令牌,即“用户未经授权”。
要检查用户是否获得授权,请使用以下代码:
func checkIfUserIsAuthorized() {
if GIDSignIn.sharedInstance().hasAuthInKeychain() {
// User authorized before
GIDSignIn.sharedInstance().signInSilently()
} else {
// User not authorized open sign in screen
}
}
